IMPROVEMENT IN SAND-PAPER HQLDER. I

A The Schedule referred to in these Letters Patent and making part of the same.

To all whom 1it may concern.-

Be it known that I, JOSEPH BARKER, of Chicago, in the county of ACook and State of Illinois, have invented an Improved "Sand-pampering Block; and I do hereby declare that the following is a full and exact description thereof', which will enable those skilled in the art to make `and use the same, reference being had to the accompanying drawings and letters marked thereon, making a part of this specification. in which- I I Figure l is an inverted perspective view of my irnproved sand-papering block.

Figure 2, a longitudinal section of the same.

Figure 3,. a section ot'a block arrangedv to sand-pa- The nature of the present invention consists in tapering thev ends of the block so as to bring the ends of the sand-paper above the surface to be smoothed, and in securing the ends of the paper by metal shoes or plates, in order that the block may pass `from one molding to another, and over uneven surfaces, without tearing the paper loose from the block; and in the novel manner in which the block is so arranged that the paper may be readily removed and replaced; also, the manner in which the angles of the paper are formed, so as not to destroy the contour of the moldings, as the whole is hereinafter fully described. 'I y j D represents a block, whose face is an exact reverse counterpart of the molding to be smoothed, and whose face ends aresomewhat tapered down, in order to bring the `ends of the sand-paper A above the faceofthe molding.

. Slice-blocks O, having 'tapering ends, and also faces conforming to the molding to be smoothed, are shod with metal plates B, which lap over the ends of the sand-paper A, and hold it firmly tothe' ends of the channels F, in which single ordouble thicknesses of w sand-paper are pnt, in order so to form an angle that the sharp edges of a molding will not be cut away, the molding shown at G pressing the paper'closely to the block, while the metal shoes'B hold the ends of the paper as aforesaid, and prevent themfrom Y catching when a series of moldings are rnnnnder the block.`

` Having thus described myv invention,

What I claim, and desire to secure by'Letters Patent, sr 1. The shoe-block O, provided with plate-metal .shoes B, when said shoes are conformed to the face of the molding to be smoothed, tapered. outward, and lapped over the ends of the sand-paper A, so as to hold itin placeon block D, as set forth.

2. The combination of -the block D, when inclined I upward at its ends, provided with grooves or channels F to' hold the angles of sand-paper A, and shoe-plate 'B,for' 1`1oldinglthe ends of tl1e'sand'paper, as set forth.

3. A sandrpapering block, consisting of the combined parts-'D141 C, dowels J, screws I, and shoes B,

when all ofthe said parts are arranged as and for the purpose set forth.
